Hindu Kush Auto | Balcony outdoor

Day 40, and thrips are still thriving 😩 Applied Protect Killer (80% Neem oil, 20% Citric acid) twice, very thoroughly, and have kept all the plants indoor - on the windowsill, with the mosquito net - for the past 5 days, and obviously they haven't been getting a proper sunbath. While I guess that no new eggs have been laid during the past 5 days, there still are tiny little thrip-bugs on all the plants (this one in particular); I have also removed some leaves - a few of which had clear signs of eggs - but I'm honestly getting quite desperate. My local growshop has suggested using Mighty Wash, which I should get tomorrow. Leaving aside all concerns regarding the buds' taste - I have read that using Neem oil on flowers almost certainly leaves a bad taste - these thrips are driving me crazy, and have thought more than once of dumping all of my plants. If anyone has any suggestion on how to save my plants - and therefore my future crop -, it'd be more than welcome.
